The Hymn to Ninkasi is at once a song of praise to Ninkasi, the Sumerian goddess of beer, and an ancient recipe for brewing (though this claim has been challenged). Written down circa 1800 BCE, the hymn is no doubt much older, as evidenced by the techniques it details, which scholars have determined were actually in use long before the hymn was written.
